Abstract
The invention discloses a production technology for an aluminium electrolytic capacitor. The production technology comprises the following steps: preparing primes, assembling and erecting, sleeving, and aging. The production technology adopts the gradient type warming and aging treatment; the aging treatment is performed in different temperature stages to enable a restored oxidation film to be more compact and to bring certain security for users; meanwhile, an aging machine is ventilated in the aging process to ensure sufficient oxygen in the aging process; and heat conducting silicone grease is added between an aluminium shell and the primes, so that the heat dissipation from the internal of the capacitor to the outside is strengthened.
Description
Technical field
The present invention relates to aluminium electrolytic capacitor technical field, specifically belong to a kind of aluminium electrolytic capacitor production technology.
Background technology
In aluminium electrolytic capacitor is produced, sub-prime stands through group and encapsulates into aluminum hull, then carries out sleeve pipe, finally by burin-in process, repairs damaged oxide-film.Current aging means be all capacitor is clamped in ageing machine aging under constant high temperature, due at high temperature once aging, the oxide-film formed is fine and close not, easily causes puncturing of oxide-film, bring certain risk to user in use afterwards.

The technical solution used in the present invention is as follows:
A kind of aluminium electrolytic capacitor production technology, comprises the following steps:
(1) prepare sub-prime: positive guide pin and negative guide pin are followed closely riveting respectively on anode aluminium foil and cathode aluminum foil, and clip electrolytic paper and be wound into fuse, fuse through changing into, carbonization, impregnation, obtained sub-prime after high temperature polymerization;
(2) vertical and sleeve pipe is organized: standing in aluminum hull by the sub-prime obtained through step (1) by organizing vertical unit, sub-prime overlapping top cement plug, then carries out sleeve pipe through jacketing machine, be prepared into aluminium electrolytic capacitor;
(3) aging: the aluminium electrolytic capacitor that step (2) is obtained is aging in ageing machine, adopt gradient type intensification burin-in process, mode every intensification in 30 minutes 20 DEG C is aging by rank, be warmed to 125 ~ 130 DEG C always, then at the temperature of 125 ~ 130 DEG C aging 2 hours, the oxide-film of aluminium foil, guide pin surface fracture is repaired.
Took a breath once in ageing machine every 10 minutes in described gradient type intensification burin-in process process.
In described step (2), group immediately, adds heat-conducting silicone grease between aluminum hull and sub-prime.
Described heat-conducting silicone grease conductive coefficient is greater than 3W/m.k, and heat resisting temperature is greater than 150 DEG C, and electrical breakdown strength is greater than 9KV/mm.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention utilizes gradient type intensification burin-in process, by carrying out burin-in process at different temperature stage, making the oxide-film of reparation finer and close, bringing certain fail safe to user; , take a breath in ageing machine in ageing process meanwhile, ensure that the oxygen of ageing process is sufficient; Between aluminum hull and sub-prime, add heat-conducting silicone grease, strengthen capacitor internal and outwards dispel the heat.
